Well no, to wake up is to get out of sleep, to get up is to get out of bed.
Um well in conversation it really doesn't matter imo. "What time did you wake up" vs "what time did you get up" means exactly the same thing... nobody makes such technical distinctions.
You could say "तुम जागकर उठते हो" to really hammer the difference but nobody says that and its just being pedantic.

Well I don't always get up right after waking up, so it's pretty important to me, I can't certify most people make the difference indeed. You might be very right, I'm just sticking to the way I have been taught.
I agree with Olivier. Quite different terms. I wake up around 6.30am but I don't get up till 7am. Sometimes I wake up in the middle of the night, and I don't get up then either. Definitely worth learning both terms.
I'm still not convinced. Both "get up" and "wake up" should be accepted.
BUT if we're going to maintain this pedantic distinction then examine the common Hindi/Urdu phrase "Utho aur Jago" - as it appears in the title of a book by Swami Vivekananda and is also the name of a morning show in Pakistan. According to you, you can't get up without waking up first so here "Utho" means "Wake up" and "Jago" means "Get up" - which in turn makes the translation of the sentence in question here "ये लोग पाँच बजे जागते हैं।" - "These people get up at five" and "These people wake up at five" is then completely incorrect.
